Letters Patent. Patented Aug. 13, 1912.

seriaiNo. 629,698.

citizenv of the United States, residing at Princeton, in the county of Bureau and State of Illinois, have invented certain new and useful Improvements in Hub-Bearings; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I a

This invention relates to hubs and more particularly to hub Construction for automobiles, carriages, and like vehicles,

An object of the invention is to construct a hub, orV wheel bearing, which 4will be Strong and durable enough to withstand the crushing strain and wear to which it is subjected and to have a life at least equal to the life of the ordinary vehicle.

Another object is to provide ahub or wheel bearing, of the above stated nature, which may be applied to axles and spindles of vasaid `rious conveyances without requirin imenh ubs to be absolutely exact in all sions;

Another object is to devisea hub, which acts as ,the bearing housing as well as the hub of the wheel.

Another object is toY provide a hub and Wheel bearing construction of the above stated character, which will be easy to man-- ufacture, on account of its shape, and which will not stick or catch, but will fit snugl enough to prevent rattllng of the parts, an another object is to yprovide a construction of this type having ball bearings and means for preventing dirt or dust from coming in contact with said bearings.

Other objects and advantages will be hereinafter set forth and pointed out in the j In the accompanylng drawings which are made a part of this application, Figure 1 is a Sectional view through the entire device, showing the spokes secured in the housing, which also constitutes'the hub, Fi 2 is a detail view of the sprin for hol in the felt washer in position, an Fig. 3 is a detail 'view of the washer.

lReferring to the drawings in which similar reference numerals designate, corresponding parts throughout the several views, 1 represents the axle having the tapering spindle 2 and the reduced threaded end 3, a suitable flange 4 being provided at the junction of thevspindle 2 and the axle 1,

said spindle having a beveled portion 5 joining with the flange 4, said beveled portion being at an-angle to said spindle 'and said' flange.

Secured upon the inner end of the spindle 2 is the collar 6, `whichhas a beveled edge 7 `:for engagement a ainstthe beveled portion 5 lof the inner end ofV said-spindle. In the outer surface or periphery of the collar 6 is the ball bearingchannel or groove 8, within which are positioned suitable bearing balls 9. Secured in a suitable groove in the peripher of the collar 6, near the flange 4, is a `sultable felt washer-retaining spring 10, the

purpose of which will presently be described.

Positioned around the collar 6 and resting upon the bearing balls 9 and partly surrounding the latter, is the cup 1l, which carries the retaining wire or spring 12 embedded in the inner surface thereof, adjacent its straight edge, which retains the cup in proper positlon in relation to the collar and also retains the bearing balls 9 within the channel 8. Positioned between the retaining wire 12 and the spring 10', is the felt washer 13, 'which is held in position by the spring 10, previously mentioned. This felt washer prevents dirt and dust from reaching the bearing balls 9 and interfermg with t-he latter or injuring them. Positloned outwardly of the cup 11 and the flange 4 1s the inner half 14 of the bearing ball houslng. Integral with this half 14 of the housing 1s the fiange 15, extending at right an les thereto and the circular spindle surroun ing' locking means. This nut 17 is provided with a beveled portion 18, opposite the beveled portion 5 of the spindle, said beveled portion 18 being at about the same angle as the spindle bevel 5, but in a direction opposite to the bevel 5. Fitting upon the smooth portion of the reduced end 3 of the spindle 2, is a collar 19, similar to the collar 6, said collar having a beveledv face 20 similar to the beveled face 7 of the collar 6. The beveled face 20 of the collar 19 engages against the.

` 25 in its inner face and outwardly of the bearing balls 22, to prevent the bearingballs 22 from slipping'out of the channel 21.

Positioned between the wire -25 and the retaining spring 23, is the felt washer 26 which, like the washer 13, prevents dirt and dust from making their way to the adjacent bearing balls. This washer is held in position by the wire 25 at one side and the spring 23 at its opposite side.

Surrounding the cup 24 is the outer half 27 of the housing, which conforms to the shape of the cups and prevents the parts from moving longitudinallyV upon the spindle. The half 27 of the housing is provided with a right angled flange 28, parallel with the flange 15 of the half 14, the half '27 having the straight circular portion 29, whichis adapted to engage upon the vouter face of the spindle surrounding portion orsleeve 16. The spokes 30 of'the wheel have their inner tenoned ends positioned between' the flanges 15 and 28, and bolts or rivets 31 are passed therethrough to hold the spokes in proper position, and at the same time hold the flanges 15 and 28 against the opposite sides ofv 4said spokes, the ends of the spokes resting against the sleeve 16 of the first half '14 of the housing. Thus it will be seen that the housing also forms the hub, a separate and distinct hub being entirely unnecessary.

The outer circular end of the half 27 of the housing is provided with threads to receive the screw threaded cap v32, which fits over the nut 17, and protects the end bf the spindle and the bearing balls, etc. carried thereupon, from the dirt and dust. This cap 32 is of sufficient size to leave a space between the nut 17 and the outer end of the spindle and said cap to prevent these parts and thus interfering with the operation of said parts'. y

Owing to the construction of the "bearing, bearing housing and hub construction combined, they may be employed upon vehicles of various types without increasing the expense of the same, but on the other hand will tend to decrease the cost of the manufacture of such conveyances, for the reason that the bearing housing also serves as the hub of the wheel, and as theaxle and spindle do not have to be manufactured with the care heretofore necessary to insure, all of the parts being of the'proper dimensions. Further, this bearing and housing may be applied to axles and spindles vof various diameters and dimensions with equally as good results and the expense of manufacturing will be greatly decreased. This construction will be highly efficient and durable and will ontlast any vehicle. The cost of repairing the spindles and hub and replacing them with new onesywill also be entirely eliminated. The bearing balls used in this device will also lastv indefinitely, as they are protected by the formation ofthe surrounding parts and the felt washer, which exclude all dust and dirt, which latter is well known as an enemy of bearings of various kinds, interfering with the operation of the bearings and wearing away the surfaces thereof,

also absorbing all of the grease and moisture from the bearings and causing them to become dry and rust. the main reason wh the cost of manufacturing will be less is due to the fact that absolute close tting of axle at collar bearing is cared for by the bevel of collar and axle at collar end and insured by nut and collar at threaded end of spindle.' Aloose fit can be made at said points and will be kept from rattling What/I claim is by the beveled sections.

It may be stated that l The combination with a s indle and a l bearing housing thereover, o collars positioned upon the opposite ends of the spindle the inner end of said spindle being bevele to receive one of the'collars thereagainst,

said collars having semi-circular channels in the periphery thereof, a nut having a beveled face and adjustably' secured Yupon the outer end of the spindle to receive the other collar thereagainst, cups around said collars, bearing balls within thel channels in the periphery of said collars, said cups resting 'upon said bearing balls, means carried by said cups for preventing the bearing balls from sliding out of said channels and also for locking cups in position around said collars, felt washers positioned between said collars and said cups, means carried by said collars to co-act with the means carried by said cups to hold said felt washers in, properv position to prevent foreign matter from reaching the bearing balls, said housing be- I-n testimony whereof I have signed mying positioned around said spindle and fricname to this specification in the presence of 1u tionally engaged against the outer surfaces two subscribing witnesses.
